automated end of line tester

How Invotec designed an automated end-of-line tester that helped one medical device manufacturer scale-up production while protecting IP The Challenge A large manufacturer of pathology solutions faced increased demands for their tissue-sampling probes. They forecasted volumes rising nearly 400% over the next five years—and they needed an additional, automated end-of-line tester to meet those goals. The company also wanted to add RFID tagging to protect their intellectual property as their products began to be sold internationally. The Solution Having designed … Read More

laser welding on medical device assembly equipment

Vision guidance is used in situations where the combination of tolerance stack-ups, beam diameter, and feature size would cause inconsistent welds. The Challenge With Precision Laser Welding When you manufacture medical devices, automotive sensors, and other intricate products, failure is not an option. With tight tolerances and complicated assembly processes, consistently laser welding complex components can be a difficult task to accomplish and maintain over a long period of time in a production environment. The focused spot diameter for laser … Read More
